Section 3 - HAZARDS IDENTIFICATION

Risk categories:

Invading ways:

Health hazard: and the upper respiratory tract mucous membrane of

conjunctival mechanism has strong stimulation. Long-term exposure to cause

chronic rhinitis, neurological dysfunction.

Environmental harm: is harmful to the environment, the water can cause

pollution of.

Flammable explosive dangerous: this product, strong excitant



Section 4 - FIRST AID MEASURES

Skin contact: remove contaminated clothing, using soap water and water to

wash skin thoroughly.

Eye contact: immediately filed with plenty of liquid water, eyelids or saline

thoroughly flushed at least 15 minutes. Seek medical advice.

Inhalation: rapidly from the field and fresh air. Maintain airway patency. If

breathing difficulties, for oxygen. If stopped breathing, perform mouth-to-mouth

breathing. Seek medical advice.

Eating: drink enough water, spits. Seek medical advice.



Section 5 - FIRE FIGHTING MEASURES

Danger: flammable vapors, which can form air explosive mixture, encounter

heat or light, and antioxidant contact, have caused combustion explosion

danger. In the air is very easy oxidation generating peroxidase, heated or

bump, even slightly friction that explosion. The fire, can occur under high heat,

make container rupture polymerization. The air is heavy steam, than in the

lower spread to quite far place, fire will burn to fire.

Harmful carbon monoxide, combustion:.

Extinguishing method: as the container to open from fire. Keep cool water

container, fire extinguishing end until. If the vessel in fire safety has become

angry or produce relinef-pressure devince, must leave. Agent: soluble foam,

powder, carbon dioxide, sand.



Section 6 - ACCIDENTAL RELEASE MEASURES

Emergency treatment: quick evacuation leakage pollution area personnel to

safety, and immediately 150m isolation, strictly limited access. Cut off fire.

Emergency workers wear self-sufficiency Suggestions are pressure ventilator,

wear anti-static overalls. Don't direct contact with the leakage. As far as

possible leakage source off. Prevent into sewer, boundary ditch, etc. The

restrictive space, Small leakage: use sand or other inflammable materials

absorption or absorption. Also can use a water washing, cleaning water diluted

in wastewater systems. A: to construct the beach or dig leakage. Using foam,

reduce steam disasters. Use explosion-proof pump metastasize to the tank or

special collector, recycling and disposal of waste disposal to place.



Section 7 - HANDLING and STORAGE

Operating note: airtight operation, provide sufficient local exhaust. Operators

must receive special training, strictly abide by the procedures. Suggest

operators wear self-priming filtering type gas mask (overall), anti-static cover,

wear clothes wear rubber gloves. Away from direct sunlight, heat and

workplace forbids smoking. Use explosion-proof type ventilation system and

equipment. Prevent steam leakage into workplace atmosphere. Avoid contact

with oxidant, alkali class. When filling velocity, and there should be controlled

to prevent static grounding device, accumulating. Equipped with

corresponding quantity and variety of fire fighting equipment and emergency

handling equipment. Empty vessels may remain pests.

Storage: store in a cool and matters needing attention, ventilated warehouse.

Away from direct sunlight, heat. Not more than 30 degrees Celsius

temperature. Packing seal, do not contact with air. With the oxidant, alkali,

edible chemicals storage reservoir, don't mix. Using explosion-proof type

lighting and ventilation facilities. Banning the use of mechanical equipment to

spark and tools. Storage areas shall be equipped with emergency handling

equipment and appropriate shelter materials.
